I just put a new engine in my 87 n/a and now it is idling at about 2000-2500 rpms. How do I fix that? I also have a bunch of stuff that has no wire/plugs for them from the wiring harness and some vacume hoses that idk where to put.....soo close to being finished, but yet still so far. I need help please I have to be able to get to class on thursday!
